Sen. Mike Lee (R-Utah) and Rep. Tom Graves (R-Georgia) have filed the Transportation Empowerment Act (TEA), according to our sister site Better Roads. The bill calls for lowering the federal fuel tax from 18.4 to 3.7 cents per gallon in the next five years.

The federal fuel taxes on gasoline and diesel raise $30 billion each year and thus are the single most important source of transportation funding for the U.S. government. Cutting the gas tax by 80 percent would drastically reduce the federal government’s contribution to transportation.

Instead, the bill would hand over authority and responsibility for funding of highways and programs to the states, Better Roads reports. The measure would also remove congressional appropriations, replacing them with block grants.
